In the drawings, 10 represents the bedframe of the machine, to which aresecured the supportirig-standard 11 and the swaginghead 12, providedwith the three rotary swaging-spindles 13, 14, and 15, (see Fig. 3,)which are actuated for revolution by means of suitable pulleys 16, whichpulleys are not shown in said Fig. 3, but are shown in other figures ofthe drawings. At the top of the swaginghead 12 is attached theframe-piece 17, which holds the wire-feeding mechanism, as shown in Fig.5 and also shown enlarged in Fig. 10, the said frame-piece beingprovided with a slot 18, the sides of which form guideways 19 19 for thereciprocating cross-head 20, which carries the clamping-jaws that serveto bring forward the feed-wire 21 from the coil, the said wire passingfirst through the stationary guide-tube 22, thence through the opening23 in the reciprocating cross-head, and thence between the clampingspring-jaws 24 of the tube 25, the said clamping-jaws being actuated toclose upon the wire by means of the lever 26, pivoted to the cross-headon the pin 27, the said lever being forked at its upper end and providedwith the adjusting-screws 28 28, which bear against the opposite sidesof the cross-bar 29 of the lever 30, formed of the connected parallelarms 31 31, which lever is pivoted at its upper end to the top of thebracket 32 and is yieldingly connected at its lower end to the slidinghead 33 by means of the cross-piece 39, (shown separately in top view inFig. 14,) to the ends 34 34 of which the lever 30 is jointed, theoppositelyprojecting cylindrical arms 35 35 beingloosely held in thecylindrical chambers 36 36 at opposite sides of the transverse notch 37,and at the ends of the cylindrical arms 35 35 are placed the spiralsprings 38 38, by means of which the yielding engagement of the lever 30with the sliding head 33 is effected. The wire is forced by means of theclamping-jaws 24 of the feeding-carrier through the passage 40 andbetween the clamping-jaws 41, (see Fig. 23,) the said jaws beingactuated to clam p the feed-wire 21 with a yielding pressure by means ofthe pressure-shoe 42, the upper portion of which is of smaller diameterthan the lower portion, thus forming a shoulder 43, against which thespiral spring 44, which is held upon the upper portion of thepressureshoe, is caused to bear, and upon the upper end of the saidpressure-shoe is placed the loose cap 45, the said cap being made torest upon the upper end of the said spring 44, so that the downwardmovement of the cap, by means of the lever 46, will serve to impart ayielding pressure upon the wire held between the clamping-jaws. Thelever 46 is actuated by means of the wiper-cam 47, in connection withthe downwardly-curved end of the said to the rock-shaft 48, which shaftis actuated by means of the toothed arm 4!) (see Figs. 15,

16, and and the upright sliding bar 50, provided at its upper end withthe rack-teeth 51 and bearing at its lower end upon the edge cam 52,held to turn loosely upon the fixed stud 53, the said sliding bar beingheld against the said cam by means of the spring 54. (Shown in Fig. Thefeed-wireis fed forward through the stationary cutting-die 55 andthrough the movable cutting-die 56, held in the sliding head 5'7, thedownward movement of which serves to cut the needleblank from the wireand transfer it to a position for engagement with thejaws of the slidingspindles of the carrier. When the wire 21 has been fed forward by theaction of the feeding-clamp and then held by the stationaryclamping-jaws 41, the milling-tool 59 of the sliding rotary spindle 60(see Figs. 15, 16, and 17) is brought forward to true up the forward endof the feed-wire, whichserves to form the rear end of the needle-blank.The

said sliding rotary spindle 60 is held in the horizontal spindle-holdingarm (31, pivoted upon the fixed bracket- (32, the said armbeing clampedto the said bracket by means of the bolt 63 and the said bracket beingprovided with the open notch 64, adapted to receive the said bolt,whereby the spindle-holding arm 61 may be turned by hand from its normalhorizontal position to the vertical position, as indicated by the dottedlines in Fig. 17, in order to obtain ready access to the end of therotary spindle for the purpose of removing the milling-tool 59 orinserting a milling-tool in the tool-holder 66 of the spindle, the saidtool-holder being shown enlarged in Figs. 18 and 19 and in enlargedsection in Fig. 22, the operation of the screw-cap 67 upon the slottedconical portion 68 of the toolholder being such as to cause themilling-tool 59 to be firmly held for rotation with the spindle, thesaid milling-tool being provided with a beveled edge 69, whereby the endof the wire 21 will be trued up in conical form, as shown in Fig. 21.WVithin the cylindrical bore 71 is secured the bearing-sleeve 72, and atthe rear of the said fixed bearing-sleeveis placed the loose sleeve 73,and between the pulley 74, attached to the spindle and sleeve 73, isplaced the spiral spring 75, which is adapted to carry the spindle toits rearward position. The rear end of the rotary spindle 60 bearsagainst the inner face of the lever 76, which is pivoted at the point 77to the spindle-holding arm 61, and the said rotary spindle is actuatedin the forward direction to bring the cutting-tool into action by meansof the cam 78, secured to the rock-shaft 48. The downward movement ofthe sliding bar 57 serves to cut off the needle-blank from thecontinuous feed-wire and carry it downward to a position in front of theforcer 79, a guiderest 80 being provided to support the projecting endof the blank. The forcer 79 is provided with a collar 81, against whichthe spiral spring 82 presses, and with an adjustable rack 95, therearward movement of the forcer being effected by means of the cam 83,secured to the rock-shaf t 84, the said rock-shaft being actuated bymeans of the rotary cam 85, secured to the hub of the cam-wheel 86, thesaid cam 85 being caused to act upon the roller 87 upon the lever 88, tothe outer end of which is jointed the connecting-rod 89, by means ofwhich connection is made to the outer end of the arm 90, secured to thesaid rock-shaft 84 The rocking movement of the cam 83 causes theholding-jaws of the rotary carrier 96, the

said rotary carrier being provided with the series of sliding spindles97, each provided with thesplitholding-jaws 98and withaforcer 99, (seeFig. 15,) by means of which the completed blank is to be discharged, thesaid holding-jaws being closed upon the inserted blank by means of theconical end 100, which is embraced by the conically-bored head 101,secured to the outer tube 102 of the sliding spindle of the carrier.Within the bore of the outer tube 102 is placed the jaw-holding spindle103, to the end of which the holdingjaws 98 are secured, and within thelongitudinal hollow of the spindle 103 is placed the forcer 99, theforward portion 104 of which is made concentric, while the rearwardportion 105 is eccentric and provided at its rear end with a projectinglug 106, by means of which the said forcer may be actuated in a forwarddirection, and having a spiral spring 107 at its forward concentricportion adapted to cause the rearward movement, the said forcer beingcaused to move forward to discharge the finished article by theengagement of the lug 106 with the fixed cam 108. (Shown in Figs. 8 and9.) The jaw-holding spindle 103 is forced forward to close theholding-jaws upon the blank by means of the wedge 109, which is forked,as shown in Fig. 25, to receive the eccentric portion 105 of the forcer,the said wedge being caused to act upon the antifriction-roller 110, andthus force the tapered holding-jaws 98 forward into theconicallyborcdhead 101,and thus closing the jaws upon the blank by meansof the spiral spring 111, which is held upon the cylindrical shank 112of the wedge between the loose rectangular washer 65 and the elongatedshoe 113, secured to the lower end of the shank 112 and loosely held inthe slot-opening 118 of the carrier, and the releasing or openingmovement of the holding-jaws is effected by means of the fixed cam 114,located at the upper side of the sleeve 115, the shoe 113 coming incontact with the said cam at every revolut-ion'of the carrier, and thuscausing the outward movement of the wedge against the inwardly-directedaction of the spring 111. The outer end of the wedge 109 is held in aslot-opening 116 made in the outer tube 102, and the rectangular washer65 is held in place by means of the shoulders 8 8, so that the outertube 102 will form the required base for the action of the wedge tocause the forward movement of the jaw-holding spindles 103 within thebore of the outer tube 102.

Upon the outer tube 102 is placed the collar 117, which serves to limitthe backward movement of the sliding spindle, the said backward movementbeing effected by means of the sliding head 33, which is held upon theshaft 119, to which the carrier 96 is secured and controlled in itsmovement by the guide 120, which serves to hold the sliding head in itsvertical position, The shaft 119 is made hollow for part of its lengthto receive the sliding spindle 121, which is connected with the slidinghead by means of the screw-threaded sleeve 122, through which thespindle passes, and between thecollar 123, which rests against theshoulder 124 and the inner end of the sleeve, is placed the spiralspring 125, and between the nut 126 and the outer end of the sleeve isplaced the spiral spring 127. The sliding spindle 121 is thusyieldinglyconnected to the sliding head. The forward end of the slidingspindle is provided with the cross-pin 128, which passes through thediametrically opposite slots 129 in the shaft 119 and into the hub ofthe disk-arms 130, the ends of which are provided with the slidingspring-actuated pushers 131, provided at their outer ends with a head132, against which the spring 133 is arranged to act, the said head 132being held by the said spring in engagement with the washer 65, which isin engagement with the sliding spindle of the carrier. Theforward-and-backward movement of the sliding head and the slidingspindle 121 is effected by means of the forked lever 134, to which isjointed the connectingrod 135, the said connecting-rod being jointed tothe lever 136, which is actuated by means of the grooved side cam 137,bolted to the reciprocating bar 138, and the stud 139 andantifriction-roller 140, which engages with the slot of the cam. Thereciprocating bar 138 is actuated in its up-and-down movement by meansof the cam-groove 141 in the face of the cam-wheel 86 and theantifrictionroller 142,held upon the stud 143. The upper end of thelever 136 is provided with the bearing-shoe 144, (see Fig. 5,) whichserves by engagement with the rear end of thelowersliding spindle 97 ofthe rotary carrier to impart forward movement to the said spindle. 4 Thereciprocating bar 138 is also provided with the attached cams 145 and146, which act upon the antifriction-rollers 147 and 148 (see Figs. 8,36, and 37) of the levers 149 and 150, the said levers being pivotedupon the rod 151 and actuated toward the face of the cams by means ofspiral springs 152 and the bearing-shoes 153. The upper ends of thelevers 149 and are provided with the bearingshoes 154 and 155, which areadapted for engagement with the rear ends of the sliding spindles of therotary carrier which lie in the horizontal plane of the axis of theshaft 119, to which the carrier is attached, so that upon the upwardmovement of the reciprocating bar the several sliding spindles of thecarrier (except the upper one) will be carried forward for the properinsertion of the blanks between the swagingdies. The shaft 119 isrotated intermittently by means of the gear-segment 156, secured to thehub of the cam-wheel 86, (see Fig. 5,) the said gear-segment engagingwith the gear 157, secured to the shaft 119, and to the hub of the gear157 is secured the disk 158, provided upon its edge with the notches159, adapted to receive the projection 160 of the springactuatedpawl-lever 161, the said pawl-lever being thrown out of engagement withthe notch 159 by means of the cam 162, which engages with the arm 163 ofthe said lever just prior to the engagement of the teeth of thegear-segment with the teeth of the gear 157, by means of which the shaftis rotated, and

by means of the notched disk and pawl-lever with the actuatingspring 167the sliding spindles of the rotary carrier are held successively in linewith the axes of the swaging-dies. The swaging-dies 164 are held in adiametrical groove 165, made in the enlarged head 166 at the forward endof the rotary swaging-spindle 15, as shown in Figs. 30 and 32, thebeating-rollers 168 being held in cylindrical recesses made in the solidframe, and the beating-hammers 169 being arranged between thebeating-rollers and the swagingdies. The swaging-spindle shown in Figs.29, 30, and 31 is the one of the series by means of which theneedle-blank is finished and its end cut off to the required length. Theswaging-spindle 15 is made hollow and provided with the driving-pulley16, and within the hollow of the swaging-spindle is held the steel tube171, provided with the transverse opening 172, in which is placed thesliding cutter 173 for severing the wire of the blank, the said cutterbeing operated to cut off the end of the finished blank by means of thecamlever 174, the face 175 of the cam being held out of engagement withthe projecting ends of the sliding forcers 176, arranged at oppositesides of the cutter and by means of which the said cutter is operated,the said forcers being held in diametrical perforations made of therecess 177 upon the continued revolu-' tion of the swaging-spindle, thesaid cutter and forcers taken together being made to fit the cylindricalbore in which the spindle revolves. The cam-face 175 is held out ofengagement with the ends of the forcers by means of the spiral spring179 and its sliding shoe 180, the said spring acting against the underside of the cam-lever 174 to press it against the stop-shoulder 182, andthe camface 175 is thrown into aposition for engagement to cut off thewire of the blank by means of the cam-operated bar 183, which carriesthe rack 91. The desired adj ustability of the movement to be impartedto the cam-lever 174 is effected by means of the adjustingscrew 184.

In front of the swaging-dies are placed the guides 185, adapted toreceive the forward ends of the sliding spindles 97 of the rotarycarrier, and thus firmly hold the same in proper alinement with'thedies, and the said guides may be provided with the side notches 186 inorder to provide for the projection of the blank operated upon from theholding-jaws of the sliding spindles of the carrier, so that theneedle-blank need not be drawn backward to clear the extreme limit ofthe guides in order to provide fort-he continued forward movement of thecarrier-spindles.

The downward movement of the sliding head 57, which carries thecutting-die 56 for severing the initial blank 9 from .the feedwire, iseffected by means of the arm 191, secured to the rock-shaft 84, the saidarm being provided with a stud 192, which enters the slot 193 made inthe sliding head, the said slot being so formed that upon the initialdownward movement of the outer end of the arm 191 a correspondingdownward movement will be imparted to the sliding head, but when theextreme downward position has been reached, as determined by theadjustable stop-nuts 194, the movement of the arm 191 will continue, thestud 192, passing into the downwardly-curved portion of the slot 193without imparting further movement to the sliding head.

The driving-cams are actuated by means of the cone-pulley 187 upon theshaft 188, at the opposite end of which is secured the gearpinion 189,engaging with the teeth of the gear 190 at the edge of the cam 85.

In the operation of the machine the millingtool is brought forward totrue up the end 'of the feed-wire 21, and then the downward movement ofthe sliding head 57 serves to cut ofi the initial cylindrical blank fromthe wire and carry it down to a position in front of the forcer 79,withthe outer end of the blank resting upon the guide-rest 80. The forwardmovement of the said forcer will then carry the blank 9 forward to aposition between the holding-jaws 98 of the sliding splindle 97 of therotary carrier 96, as shown in Fig. 15, the said jaws-being opened toreceive the blank by means of the cam 114, and upon the subsequentrotary movement of the carrier by means of the gear-segment 156 theblank will be carried by the holding-jaws to a position in front of thedies of the rotary swagingspindle 13. Then the action of the cam 145,attached to the reciprocating bar 138, will cause the forward movementof the carrierspindle 97, the projecting forward end of the said spindlepassing into the cavity of the.

guide 185, which serves to hold the said end so that the blank to beoperated upon will be held in true line with the axis of the dies, andsimultaneously with the forward movement of the carrier-spindle 97 bythe action of the cam 145 the action of the cam 137 upon the lever 136will cause the backward movement of the sliding head 33, and theconnected spring-actuated pusher 131, which serves to hold the rear endof the carrierspindle in close contact with the bearing-shoe 144 of thelever 136, and by means of the yielding pusher 131 variable forwardmovement may be imparted to the carrier-spindle under a uniform yieldingpressure. When the blank has been operated upon by the dies of theswaging-spindle 13, and thus reduced from the cylindrical form shown inFig. 44 to the form shown in Fig. 45, and the direction ofv the movementof the cam 137 reversed, causing the withdrawal of the blank from theswaging-dies, the action of the rotary gearsegment 156 will cause therotation of the carrier, so that the blank will be carried to a positionin front of the swaging-spindle 14. Then the action of the reciprocatingcam 137 upon the lever 136 will effect the forward movement of thecarrier-spindle 97 to carry the blank between the dies of the saidswaging-spindle to cause the further reduction of the form of the bla nk to i he form shown in Fig. 46, and upon the withdrawal of the blankfrom the said dies by the downward movement of the cam 137 the continuedrotary movement of the carrier will carry the blank to a position infront of the swaging-spindle 15, and the action of the cam 146 upon thelever 150 will serve to carry the blank between the swaging-dies of thesaid spindle, and by means of the said dies the blank will be stillfurther reduced and extended, as shown in Fig. 47, and its end trimmedto the required length by means of the sliding cutter 173. The blank isthen withdrawn from the dies by the down ward movement of the cam 137,and upon the continued rotation of the carrier the shoe 113 of the wedge109 will engage with the cam projection 114, whereby the holding jaws 98will be opened to release the blank, and at the same time the lug 106will engage with the fixed cam 108 to effect the forward movement of theforcer 99 to cause the discharge of the finished blank from the jawspreparatory to the reception of a fresh cylindrical blank as before.

By the employment of the fixed cam 108 for discharging the finishedblank when'the carrier is in motion instead of discharging the blankwhen the carrier is at rest I am enahled to dispense with one of thesliding spindles which would otherwise be required in the carrier, whichconstitutes a desirable improvement.

Any desired number of rotary swagingspindles may be employed incombination with a rotary carrier having sliding spindles andholding-jaws for transferring blanks from the swaging-dies of one rotaryspindle to the swaging-dies of another spindle in connection with meansfor inserting the blank between the holding-jaws, and means fordischarging the finished blank.

I claim as my invention- 1. In a machine for making needle-blanks orsimilar articles, the combination of means for feeding the wire forward,and clamping means fpr holding the wire in its forward position, with arotary cutter for milling the forward end of the wire, the reciprocatingcarrier provided with a cutting-die adapted to hold the milled blankwhen severed from the wire, and the forcer for forcing the sev eredblank endwise and forwardly from the cutting-die, when the carrier is inits delivering position, substantially as described.
